Abstract: The effects of seven ectomycorrhizas including Suillus luteus(L.:Fr.)Gray, Cantharellus cibarius Fr., Pisolithus tinctorius(Pers.), Cenococcum geophilum Fr., P. tinctorius(Pers.)Coder et Couch, Lactarius deliciosus(L.:Fr.)Gray on growth, physiological characteristics and nutrition in Pinus massoniana seedlings were studied in greenhouse. The results showed that ectomycorrhiza could significantly improve the growth of seedling shoot, ground diameter, lateral root and could increase number of lateral root and accumulation of biomass by inoculating with Suillus luteus(L.:Fr.)Gray, Cantharellus cibarius Fr., Pisolithus tinctorius(Pers.)and Cenococcum geophilum Fr. Inoculation with P. tinctorius(Pers.)Coder et Couch and Lactarius deliciosus(L.:Fr.)Gray had no significant influence on growth of seedling height, diameter and biomass compared to control group. The ectomycorrhiza could significantly increase the moisture content of seedling, the content of chlorophyll, activity of nitrate reductase and content of soluble sugar, strengthen absorptive ability of root, reduce the content of proline and MDA. The ectomycorrhiza could significantly improve the absorption of P and K compared to N. The ectomycorrhiza reduced the allocation of N, P and K in root of seedlings but increased the allocation of K in stem and P in leaf compared to control group. Generally, inoculation with S. luteus(L.:Fr.)Gray, C. cibarius Fr., P. tinctorius(Pers.)Coder et Couch, C. geophilum Fr. had preferable effect on growth, physiological metabolism, absorption of N, P and K. And there was a poor effect after inoculation with P. tinctorius(Pers.)Coder et Couch and L. deliciosus(L.:Fr.)Gray.
